DNA is located within the nucleus of the cell and is always double-stranded in living organisms. DNA houses genes, which are permanent from the day that someone is conceived until their death (given there are no mutations). RNA on the other hand is transient within the cell and ...
What is ATP in biology? Besides making ATP, what are two things cells power with proton gradients? 1. What is ATP? 2. What is ADP? 3. Why does energy need to be transferred from glucose to ATP? Which of the following options is correct? The driving force of facilitated diffusion...
What is ADP and NADP? ATP -Adenosine triphosphate.ADP - Adenosine diphosphate.NADP - Nicotinamide adenine dinucleotide phosphate. NADPH - The reduced form of NADP. In the Light Dependent Processes i.e Light Reactions, the light strikes chlorophyll a in such a way as to excite electrons to a ...
which is then fixed by rubisco and made into sugars in the Calvin cycle (just like C3 photosynthesis). C4 plants are better adapted to hot, dry environments and can continue to fix carbon even when their stomata are closed (as they have a clever storage solution), according to Biology ...
Nucleotides are just one part of the intricate world of cellular biology. They play acentral role in the life and structure of DNA and RNA, and their function is incredibly important in the buildup and breakdown of cells. Our cells are carefully working together every day, and understanding ...
The 3 energy systems work either together or on their own to find that missing phosphate and slam it back into ADP to make more ATP. The phosphocreatine system is fastest but doesn’t last long. Aerobic energy production yields most adenosine triphosphate… but it’s laborsome and slow. ...
Deoxyribonucleic acid, or DNA, may be the most famous single molecule in all of biology. The discovery of its double-helix structure in 1953 catapulted James Watson and Francis Crick a Nobel Prize, and even among non-science nerds, DNA is widely known for playing a major part in the innum...
As well as its essential role in energy creation, NAD+ is also used by enzymes for various functions. Poly-ADP-ribose polymerases, or PARPs for short are one such group of enzymes. They attach parts of the NAD+ molecule to other molecules. There are 17 different PARPs in human cells and...
What is RNA and DNA (in biology)? What is a subunit of nucleic acid formed from simple sugar, a phosphate group, and a nitrogenous base? Which base is used in RNA but not DNA? Which base is used in RNA but not in DNA? Which specific subunits are associated with each of the four ...
Explain the processes of ATP hydrolysis and ADP phosphorylation. Describe how ATP is produced in mitochondria from the products of the previous steps of cellular respiration (NADH and FADH_2). (Via the electron transport chain) Explain the TCA cycle and the electron transport chain. ...
